Definition of
Alfonso el al (2008), Med Phys 35 (11):
a class of dynamic or step-and-shoot
delivery fields, or a combination of fields,
such that full CPE is achieved in a time
IAEA/AAPM formalism for reference dosimetry
composite MV photon fields
average sense at the position of the detector
Bouchard et al (2012), Med Phys 39 (3)
Formal proof that CPE cannot be practically achieved in a finite volume in external beam
RT.
Proposed new definiton of PCSR field:
a field that represents a class of dynamic or step-and-shoot delivery fields, or a
combination of fields,
such that the absorbed dose distribution is uniform at the position of
the detector, as opposed to conventional RT in which a dose gradient is present.
